Submitting Your Application

The first step in joining Voyage Advisory as a Data Analyst is to submit a compelling application that reflects your technical skills and passion for the role. Whether you were contacted by a recruiter or have applied on your own, it’s crucial to carefully review the job description and tailor your CV according to the prerequisites.

This interview, lasting about an hour, will focus on your proficiency with SQL, MuleSoft, GraphQL, and data integration architecture, among other technical skills.

For data analyst roles, expect take-home assignments involving product metrics, analytics, and data visualization. Your knowledge of hypothesis testing, probability distributions, and machine learning fundamentals may also be assessed.

Depending on the seniority of the position, real-scenario case studies may be assigned.

Onsite Interview Rounds

After another recruiter call to outline the next steps, you will be invited to the onsite interview loop, which consists of multiple rounds. During your day at Voyage Advisory, your technical skills, including programming and data modeling capabilities, will be thoroughly evaluated.

You might also have to present the take-home exercises if assigned earlier. This rounds off the holistic assessment of your candidacy against other finalized candidates.
